摘要:
A method for producing a ceramic honeycomb structure having a large number of paths partitioned by porous cell walls, the cell walls having thickness of 0.17-0.45 mm and porosity of 40% or more, comprising the steps of preparing a moldable material comprising a ceramic material powder, a binder, a pore-forming material and water, extruding the moldable material to form a honeycomb-shaped green body, and drying and sintering the green body, the pore-forming material having a melting point of 40-110°C, being solid in the moldable material, and being melted in the drying step so that 25% or more thereof is removed from the green body in the drying step.
摘要(中):
一种陶瓷蜂窝结构体的制造方法,其特征在于,具有由多孔质细胞壁分隔的大量路径,所述细胞壁的厚度为0.17〜0.45mm,孔隙率为40%以上,其特征在于,包括以下步骤: 粉末,粘合剂,成孔材料和水,挤出可模制材料以形成蜂窝状生坯,并且干燥并烧结生坯,成孔材料的熔点为40-110℃, 在可模制材料中是固体,并且在干燥步骤中熔化,使得其在干燥步骤中从生坯中除去25%以上。
